1、Chemical Name:  Copper Sulfate

2、Molecular Formula : CuSO₄·5H₂O

3、Molecular Weight: 249.7

4、CAS: 7758-98-7

5、Character: It’s dark blue triclinic crystal or blue crystalline powder or granule. It smells like nasty metal. It effloresces slowly in dry air. Relative density is 2.284. Above 150℃, it loses water and form Anhydrous Copper Sulfate which absorbs water easily. It’s freely soluble in water and aqueous solution is acidic. PH value of 0.1mol/L aqueous solution is 4.17（15℃）. It’s freely soluble in glycerol and dilute ethanol but insoluble in pure ethanol.

6、Usage: It is used as nutritional supplement, antimicrobial agent, firming agent and processing aid.

7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
